6、 Supplement 3 to ITU-T H-series Recommendations Operator requirements for full-service VDSL in ITU-T Recommendations H.610 and H.611 Summary This Supplement is based on the Full-Service VDSL Focus Group Technical Specification (FGTS) Part 1 “FS-VDSL Operators Requirements“ and complements the specif
7、ications found in ITU-T Recs H.610 and H.611. Source Supplement 3 to ITU-T H-series Recommendations was agreed by ITU-T Study Group 16 (2001-2004) on 30 May 2003. ii H series Supplement 3 (05/2003) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in t
8、he field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
9、The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolutio
10、n 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this publication, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a r
11、ecognized operating agency. Compliance with this publication is voluntary. However, the publication may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the publication is achieved when all of these mandatory provisions are met. The words “
12、shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the publication is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the pr

19、611 define the architecture and operations, administration monitoring and provisioning (OAMP) requirements for the delivery of video, data and voice services across a VDSL access network to an in-home environment, known as a Full-Service VDSL (FS-VDSL) network. This Supplement provides the operator
20、requirements for services and infrastructure deployment upon which these Recommendations were based. The intent was to maximize commonality of the operators requirements to help vendors to implement common products, which can then be offered in all international markets thereby achieving economies o
21、f scale. The Recommendations aim to enable the provisioning of a bundle of triple-play services in a reliable way, with minimal user intervention, respecting the key requirements of security and conditional access to the content and at a cost compatible with mass market deployment. Only the elements
22、 that need to be specified to achieve an interoperable low-cost platform are included in these specifications. It is intended that each service provider can define and evolve a distinct portfolio of competitive services using the bricks defined in the Recommendations with downloadable software confi

VDSL is referenced throughout the Supplement as the physical layer technology; however, the architectural specifications contained herein could be equally applicable to CPE and Access Networks employing other broadband physical layer technologies. 2 References The following references are
